Puzzle Games
Classic puzzle games with a straightforward goal: clear the board, fill the grid, or find the path. Each game has five difficulty levels from beginner to Einstein.
Minesweeper
Clear the board without hitting a mine. Pure logic.
Nonogram
Fill cells to reveal a hidden picture using row and column number clues. Also called Picross or Griddlers.
Mazes
Navigate from start to finish through a maze of passages. Online play with hints, or print for offline solving.
Tower of Hanoi
Move a stack of graduated disks between three pegs. Never place a larger disk on a smaller one.
What each game asks of you
Minesweeper is probability and edge-reading. Each revealed number tells you how many mines sit in adjacent cells, and your job is to figure out which cells are safe to click. In easier grids the logic is straightforward. In harder ones, you will run into spots where two configurations are equally possible, and you either find a clue elsewhere on the board or make a calculated guess.
Nonogram flips the idea — instead of placing numbers, you fill cells to reveal a hidden picture. Row and column clues tell you how many cells to shade and in what groups. Also known as Picross or Griddlers.
Mazes are pure navigation. You see the whole grid and need to find a path from the start cell to the exit. Easy mazes are small and mostly straightforward. Harder ones grow larger, pack in more dead ends, and force you to backtrack when a promising corridor hits a wall. The expert and einstein sizes are big enough that keeping your bearings becomes part of the challenge.
The five difficulty levels
Easy gives you a lot of information up front, so you can learn the mechanics without getting stuck. Medium removes some of that safety net. Hard is where most regular players settle once they know the game. Expert requires advanced techniques that beginners haven't encountered yet. Einstein is the ceiling: puzzles designed to be solvable but genuinely difficult.
You can start at any level. If easy feels too slow, skip straight to hard. There's no unlock gate.
